Question

Quizplus · Accepted Answer

Homologous structures are defined as structures that share a common evolutionary origin, but may have different functions in different species. The presence of homologous structures is due to the same genes or developmental pathways that direct their development, making choice C correct. Choices A and D are incorrect because homologous structures may serve different functions in different species and can be found between different species. Choice B is also incorrect because homologous structures are formed from the same developmental pathways.
